MEGATRO 345KV SINGLE CIRCUIT OVERHEAD LINE STEELTUBULAR POLE is 11.5 miles long and built with single, concrete and tubular-steel poles. The conductor is a vertical 2-bundle 795 kcmil Drake ACSR per phase. conductors are supported from polymer braced-post insulators. The line has one 48-fiber optic shield wire (OPGW). Average span lengths are 800 feet long and the route includes seven angle poles which are supported with guys and anchors.
MEGATRO determined the environmental loadings for the project and prepared the preliminary and final design. MEGATRO provided assistance to the Owner for Right-of-Way easement acquisition, prepared transmission line unit assemblies, line guying and anchoring assemblies, guy arrangement drawings, and construction specifications. MEGATRO prepared Bid Document Notebooks for Rosendin to acquire construction bids and material. MEGATRO also prepared "For Construction" project notebooks with all necessary drawings, staking sheets, and stringing charts.
MEGATRO coordinated with Rosendin throughout design and construction periods, and provided consulting assistance, as needed to the project owner.
Design work for which MEGATRO was responsible: 100%
MEGATRO can optimized design and make tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials, especially in tower design, we can make final weight lower, with maximum utility of material and make total structure more strong and sturdy. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 345KV double circuit tower, and offers a variety of designs to meet client specific.
Our main design engineer from USA, can use PLS &TOWER software to design every type steel tower based on structural calculations and geometrical frame drawings. To meet the expectation, we produce shop drawings, components list and full production documentation, and even complete 3D models that facilitate the elimination of all design and drawings errors generated on the drawings. Another advantage is our 3D design and loading & design report, and can optimized the design and save cost for our clients.
MEGATRO had professional QA &QC team to control quality and execute strict QC & QC plan as per client requirements. MEGATRO is one of the few manufactures who assemble a face of 345KV overhead transmission line steel tower. After fabrication all 345KV double circuit transmission line steel tower, are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.
MEGATRO is one of the few manufactures who assemble a face of every tower section. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies.
